I am not sure if I mentioned it earlier in this thread, apologies if I did, but Verne Gagne vs. Mad Dog Vachon for the AWA title in the Montreal Forum from 1972 exists. I saw a two second clip about 17 years ago and had it confirmed last year that the match itself has survived. Aaron Wiess owns it. He aired it at a sports festival last year in Toronto and I have not run across anyone that actually saw it but it was advertised along with a few other gems.
So, it's a match I know exists, and I am hopeful that Aaron puts it out there in a place more people can see it someday. Verne and Dog had a historic AWA feud and aside from seeing them actually match up vs. each other, it would be nice to put some context to how big a deal it was when Verne and Dog eventually got together in 1979 and won the AWA Tag titles.
There are other things out there that may not exist that the LBOA release has given me hope on, such as Bock-Backlund from Toronto in 1979 and of course Flair-Backlund from the Omni. But I know Verne-Dog exists, which makes seeing it something more tangible for me at this time.
